The rest of the models in the "green" line are 7200 RPM would be willing to be this one is as well.

Umm, no. The Blue and Black lines are 7200rpm. The Green series are all 5400rpm.

Well, I think they increased the RPM of the "Green" class drives so yes, the 3 TB models are now running at the same spindle speed.
I have a WD30EZRSDTL and a WD30EZRX when I retested both drives, the WD30EZRX was about 10.6% faster than the WD30EZRSDTL on average. See the platter profile too - there was an almost uniform increase in transfer rates across the platter.
So, unless there was any change to the platter's areal density, the only thing that can account for the increase in platter throughput would be an increase in spindle speed.

And on top of that this is what I was able to find on Google.

I'd be glad to check out the check out the platter profile, except you didn't provide it. Whoops, because you copy/pasted from another forum without attribution:

That said, I can't actually confirm either way because Western Digital doesn't list an actual number for the RPM of the Green drives -- they just list "IntelliPower". It's possible that they recently changed it (perhaps to a variable RPM depending on load?) but I haven't actually been able to find much concrete evidence.

The green drives are capable of 7200rpm, which is their listed specs.

I was under the impression they were 5000-5400 rpm in actual speed.. and I thought I read that on HardwareCanucks, but their site is down for me right now.
